LEONARD Z. PRESTON, OF LEAVIENWOBTH, KANSAS.

CI-IUBN.

Application filed January 22, 1913.

To all whom it may concern:

Be it known that I, LEONARD Z. PRESTON, citizen of the United States,residing at Leavenworth, in the county of Leavenworth and State ofKansas, have invented certain new and useful Improvements in Ghurns, ofwhich the following is a specification.

This invention relates to an improvement in churns.

The primary object of the invention is to provide a construction inwhich the churning may be accomplished in a comparatively short time andby the use of a comparatively small amount of power.

A still further object is to provide a construction which may be quicklyassembled and the churning members easily cleansed.

Another object of the invention is to provide a construction in whichthe cream will be acted upon by interdigitated fiat perforated memberswhich move in different directions and at different speeds, therebyproducing a more effectual churning mechanism than where the agitatingmeans rotate in the same direction and produce merely a stirring action.

In the drawings; Figure 1 is a side elevation; Fig. 2 is a verticalsection; Fig. 3 is a top plan View; Fig. 4 is a section on the line 4-4of Fig. 1; and Fig. 5 is a detail view of a portion of the agitatingcylinder.

In the drawings, designates a base which is provided with a cylinderreceiving member 11, the member being formed with curved slots 12. Acylindrical receptacle 13 is received within the base, said receptaclebeing provided with projections 14 which extend within the slots 12, thereceptacle being rotated to dispose the projections 14 at the base ofthe slots, thereby locking the receptacle against movement with respectto the supporting member 11. The receptacle 13 is of the usualconstruction being provided with a bearing 15 at its base.

A perforated cylinder 16 is arranged within the receptacle 13, saidcylinder being connected at its base by means of transversely disposedarms 17, one of which is formed with a projection 18 which sits withinthe bearing 15 of the receptacle. The cylinder is in this mannersupported to rotate within the receptacle 13. The cylinder is providedwith perforations 19 which are substantially semi-circular, a Web 20extending between the semi-circular apertures. Blades 21 are securedinteriorly of the cylinder 16, said Specification of Letters Patent.

blades being formed with perforations 22, similar to the perforations inthe walls of the cylinder. These blades are of a number consistent withthe height of the cylinder and are disposed one above the other, theblades being preferably disposed at diametrically opposite points withinthe cylinder. A gear 23 is secured to the upper edge of the cylinder,said gear being driven, in a manner to be hereinafter described, torotate the cylinder on its bearing.

A cover 24 is disposed to rest upon the receptacle 13, the cover beingformed with a downwardly disposed member 25 which extends within thesockets 26 formed integral with the receptacle. A bearing block 27 issupported by the cover, said bearing supporting a shaft 28 on which ismounted a sheave 29 over which a drive belt passes. A gear 30 isarranged on the terminal of the shaft 28 remote from the sheave 29, saidgear meshing with a pinion 31 which is supported by a bracket 32. Itwill be noted by this construction that when the shaft 28 is rotated thepinion 31 will be driven.

A plurality of brackets 33 are disposed on the under face of the cover24, said brackets supporting the circular member 34, the periphery ofwhich is provided with a packing 35, the circular member forming a closure for the cylinder 16. A bracket 36 is supported by the cover 24 andis secured to the cover 24. This bracket supports a bearing block 36, ashaft 38 being supported for rotation by this-block. A gear 39 ismounted on one terminal of said shaft, said gear meshing with the gear34 which is mounted upon the cylinder 16. A pinion 40 is arranged on theterminal of the shaft 38 remote from the gear 39, said gear being drivenin a manner which will be herein after described.

A paddle 41 is arranged within the cylinder 16, the transverse beam 17of the cy1- inder being formed with a bearing 42. The base of the paddleshaft is provided with a projection 43 which extends within saidbearing. A plurality of blades 44 are carried by the paddle, said bladesbeing formed integral with the plates 45 which are secured to the sidesof the paddle shaft. The portion of the shaft which is disposed withinthe cylinder 16 is square in cross section. These blades are providedwith perforations 46 and are so disposed with respect to the blades 21of the cylinder 16 that when the paddle is rotated, the two sets ofblades will interdigitate. The portion 47 of the paddle shaft 42 iscylindrical. The upper portion 48 of the shaft is hexagonal, the cover 21 being provided with an opening through which the shaft extends. Thebracket 36 is provided with an arm 49 which supports the pinion 50. Thispinion is provided with a hexagonal. bore through whichv the hexagonalportion 48 of the shaft extends. The pinion 31 is provided with ahexagonal bore and the upper portion of the shaft ext-ends within thispinion.

It will be noted that when the shaft 28 is driven by any suitable sourceof power that the paddle shaft will be rotated by means of the pinion31. As the paddle shaft is rotated the pinion 50 will mesh with thepinion 40 mounted on the shaft 38 which will rotate the shaft 38. Thegear 39 will mesh with the gear 34: rotating the cylinder 16. Itwill beseen by this arrangement of the gears that the paddle and the cylinder16 will rotate in opposite directions and at different speeds, theliquid thus being agitated by the interdigitating blades which travel indifferent directions and at different rates of speed.

It will be noted that the material circulates through the blades of thepaddle and the cylinder 16 and that it passes through the base of thecylinder 16 as well as through the side walls thereof.

By this construction it will be seen that the cream may be churned in acomparatively short space of time and without the utilization of theamount of power usually necessary when either single or double dash-eractuating mechanisms are used.

Particular attention is called to the manner in which the shaft andagitating members are assembled and the fact that they may be readilydisassembled for the purpose of cleaning, that is the paddle and the twocover members may be lifted from the receptacle and the paddle memberreadily cleansed. The cylinder may also be removed from the receptacleand the interior of the receptacle, after the butter has been removed,easily cleaned as there are no obstructions to hold the material.

lVhile the term cylinder has been used, and both the inner and outerreceptacles are shown as cylindrical, attention is called to the factthat the receptacles may be of any suitable configuration, the operationof the mechanism in no way depending upon the shape of the receptacles.

I claim 1.
